Answer:
The second step is wrong. It should be -6y =12 so y-intercept is -2
Step-by-step explanation:
Answer:
The 3-dimensional shape created will be a cone
Step-by-step explanation:
step 1
Plot the points
we have
A(0, 0), B(0, 5) and C(3, 0)
The figure is a right triangle
see the attached figure
so
When this shape is rotated about the y-axis, the 3-dimensional shape created will be a cone
where
AC is the radius of the base of cone
The radius is equal to r=AC=3 units
AB is the height of the cone
The height is h=AB=5 units
BC is the slant height of the cone
Applying Pythagoras Theorem

Problem 2
<h3>Answer: Choice C) 3+5 = 5+3</h3>
The commutative property of addition is the idea of adding any two (or more) numbers in any order we want. In the example above, the 3 and 5 swap places. You can think of them commuting back and forth as if they are going from work to home (or vice versa).
A similar property is the commutative property of multiplication. An example would be 2*3 = 3*2 (shown in choice B).

Problem 3
The list of choices is not showing up, so I cannot answer this one. Please update.
This is a really hard question. I can’t help you
Square units are the units of measuring area. Therefore, this question asks for the area of the room.
The room has the shape of a rectangle with:
length = 13 units and width = 9 units
The are of the rectangle can be calculated using the following rule:
area of rectangle = length * width
area of the room = 13 * 9 = 117 square units
